COMBINED PACKIN- G AND VALVE.

SPECIFICATION forming part of Letters Patent No. 568,669, dated September 29, 1896.

Application filed February 10, 1896. Serial No- 578,643. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. ELLs-- WORTH, of Cleveland, Cuyahoga county,

- Ohio, have invented certain new and useful Improvements in a Oon1bined-Packing' and Valve; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same. 7 1 I My invention relates toan improved combined packing and valve for beer-pumping and the like apparatus; and it consists in the peculiar formation of said combined packing and valve whereby the tapping-tube may be inserted into the barrel or keg without the lower end of the bung being plugged, all of which will be more clearly'hereinafter set.

forth and claimed.

In the drawings, Figure 1 is a view in longitudinal vertical section of a bung embodyingmy invention, showing my improved com- Figs. 2, 3,'and 4 are views of my improved combined packing and valve, showing its construction more clearly and representing it in different positions; and Fig. 5 represents my improved combined packing and valve provided with side ribs for reinforcing the same,

A represents a bung, of usual or preferred construction, having an opening through it for the passage of the tube B. I

A represents the bung-cap, which is constructed so as to engage the upper end of the bung A and form, in connection with the upper end of the bung, achamber for the reception of the packing.

0 represents my improved packing,-which is made of yielding or elastic material, preferably of rubber, and thick enough so that by pressure against one or both of its aces,

its central opening will be diminishedand caused to tightly hug the tube B.

Extending downward from the packing C is a hollow conical projection O, which-is :slit or out at 0 into two equal halves, the said slit extending to the packing C, so as to allow it to readily open when the tube B is pushed downwardly, as shown in Figs. 1 and 3, and embrace the tube. By thus splitting the said conical projection C," to the bushing extending but a short distance into the barrel or keg; also, by making said conical portion short and forming it with a pointed or V- shaped rather than a rounded apex the two halves will embrace the tube more closely when it is inserted for the purpose of withdrawing the contents. Preferably the conical portion is slit or bisected directly through its apex in orderethat the pressure on the two halves may be equal, thus closing, the opening more effectually when the tube is withdrawn, as shown in Figs. 3, 4, and 5.

The object of the conical extension (3 is to do away with plugging or corking the lower beer when first tapped contains more or less gas, and hence it is always under pressure.

and would splash or force itself out if an opening were left through the bung, as would be the case when the tube B is withdrawn, as is necessary before a fresh keg of beer is tapped, and hence the necessity of closing the opening through the bung before begin-v As heretofore stated,

ning the operation. this had been done by plugging the lower end of the bung by means of a valve or with a cork and afterthe' bung was inserted and driven home the tube B was pushed downward and the valve opened or the cork driven out.

' With my improved device the tapping-tube is simply inserted through-packing c and valve 0', whereby a tight joint is formed around the same. by means of my device the tube, when necessary; may without any inconvenience be withdrawn after having been inserted.

In Fig. 5.1 have shown the conical portion 0' of the packing 0 provided with two ribs 0 0?, one on each lip or side. The object of these ribsis to add to the resiliency of these parts and reinforce them when considered necessary.

What I claim is- 1. The combination in a combinedpacking and valve of the bushing which forms the packing for the tapping-tube; a conicalshaped portion integral therewith provided It will also be seen that With an approximately V- shaped apex and bisected by a split extending to the said bushing, the whole being formed of rubber or similar elastic material; a bung for receiv-- ing the packing and conical portion and a tapping-tube adaptedto pass through the slit in said conical portion andxbe clamped by the bushing, substantially as described.

' 2. In a combined packing and-valve for a beer keg', thc'c'ombination" with a bushing which forms the packing for the tappingtube and a conical-shaped portion integral with said bushing, the said conical portion composed of two symmetrical closely-fitting halves or lips independent of each other, and

each provided Witha reinforcing-rib, the whole formed of rubber or similar elastic n1aterialyof a bung for receiving the packing or bushing and the conical portion integral therewith, and a tapping-tube adapted to 2 pass through the slit in the depending portion and be clamped by the bushing, substantially as shown and described.

In testimony whereof I sign this specification, in the presence of two Witnesses, this 6th 2 day of January, 1896. v

I WILLIAM E. ELLSWORTH.
